Square Enix is planning on bringing Dragon Quest I through Dragon Quest VIII to smartphones, but they aren’t releasing the games in order. Japan get Dragon Quest first then Dragon Quest VIII. Next up is Dragon Quest IV: Chapters of the Chosen since Square Enix is starting to talk about the smartphone version.
Dragon Quest IV uses the same control system as Dragon Quest VIII. The games are designed to be played with one hand and use a popup joystick to move around the field. Square Enix fine tuned the game by adding five battle speed settings and a quicksave feature so you can save your game even when there isn’t a church nearby. Dragon Quest IV also has the extra story chapter from the Nintendo DS remake which was localized for the West.
Square Enix is also preparing a patch for Dragon Quest VIII that addresses memory crashing bugs, battle tempo, and adds new alchemy recipes.
